Info about medical condition and martial arts

Well, my cousin has a problem in his right leg, is congenital dislocation of the hip. He has 24 years, so the doctor says now. He's ok to practice martial art; but which one you thinks is more appropiate for him.

prolly ought to talk with an ORTHO who specializes in sports medicine. mine (unfortunately retired a few months ago) was really helpful and could address issues about lifting/training for contact sports, grappling, etc.

larger teaching hospitals or university hospitals may have such a specialist.
